Cell culture inserts/microporous membranes promote the proper phenotype of a variety of endothelial cells including kidney cells, intestinal epithelial cells and others. Equally as important is the fact that these devices can be used to study transcytosis, a process discussed briefly in the cell culture lecture.

What is transcytosis and why does the device described above allow one to study this process compared to a typical, plastic cell culture plate?

Although the two theories differ on the evolutionary path of dinosaurs, they agree that

What kind of seafood would you expect to have the highest levels of mercury and why? kelp, because they use the sun to photosynthesize on the bottom trophic level. oysters, because they filter feed on plankton on a lower trophic level. small fish, because they eat plankton on a higher trophic level. sharks, because they feed on organisms on a higher trophic level.

Fruit bats in central america eat bananas and other fruits. banana plants rely on bats for pollination. what would be the most likely consequence on the banana crop if fruit bats were eliminated from the area? the banana crop would increase because bats would stop eating the crops. the banana crop would decrease because bats would no longer pollinate the crops. the banana crop would remain constant because bees would replace the bats. the banana crop would remain constant because the plants would adapt using asexual reproduction.
